Morgan State University “Growing the Future, Leading the World”™

CE FLUID MECHANICS RESEARCH LABORATORY

Fracture Mechanics, Plasma Aerodynamics, Heavy Lift

Morgan State University is embarking on cutting-

edge research in the areas of heavy lift, fracture mechanics,

plasma aerodynamics and super cavitation. As such, Morgan

is fortunate to have approval for additional assets, such as

subsonic and supersonic wind tunnels, with access to

hypersonic wind tunnels located at the Department of Defense

White Oak, Maryland Facility. Moreover, Morgan is a user of

NASFRO, ANSYS, FLUENT, CFX and NASA

OVERFLOW2. Finally, Morgan has past experience with

NASTRAN.

This lab will host research focusing on Fracture

Mechanics (fracture growth and failure in airplane parts and materials),

Plasma Aerodynamics (modeling and simulation), and Heavy Lift (space travel assistance) activities.

FRACTURE MECHANICS

Internal crack growth may inhibit the safe air travel of passengers in both the commercial

and military sectors. Using NASGROW and ANSYS along with the Finite Element Modeling

(FEM) Methodology fracture growth and failure analysis in airplane parts and materials was

studied. The Boeing 787 Dreamliner was the identified aircraft to be researched against material

abnormalities. Moreover, failure analysis plays a critical role in our transportation sector.

PLASMA AERODYNAMICS

Plasma Aerodynamics has a bright and promising in the aerodynamics area. Decrease in drag

potentially 10–30% as well as creating invisible radar signature. Morgan State University is in the initial

stages of modeling and simulation of this critical and revolutionary area. The European Space Agency and

others have capitalized on the initial work done in Russia. Aircraft bodies immersed within a plasma field

will increase lift-to-drag ratio, thus allowing a fuel cost saving within the transportation sector. Moreover,

underwater supercavitation offers the same.

HEAVY LIFT

Morgan State University proposes and is actively seeking research in heavy lift to assist in space travel for

the race back to the Moon. Morgan is a user of Satellite Tool Kit (STK) and ARcView-ARcInfo and can

assist in trajectory plotting for this lunar mission. Heavy orbital lift becomes a major player for on-orbit

travel and exploration.

Measuring fluid density and relative density (specific gravity) of a liquid using a universal hydrometer

Measuring fluid viscosity using a falling sphere viscometer

Measuring fluid density and relative density (specific gravity) of a liquid using a pycnometer (density

bottle)

Observing the effect of capillary elevation between flat plates

Measuring the effect of capillary elevation inside capillary tubes

Verifying Archimedes principle using a brass bucket & cylinder with a lever balance

Measuring atmospheric pressure using an aneroid barometer

This apparatus introduces students to the following properties of fluids:

Viscosity Capillarity – capillary elevation between flat plates and in circular tubes

Buoyancy (Archimedes’ principle)

Atmospheric pressure

The apparatus consists of a collection of components that demonstrate individual fluid properties. The

components are stored on a common support frame manufactured from PVC with circular spirit level and

adjustable feet for leveling. The apparatus is designed to stand on a suitable bench top, where some of the

components can be operated independent from the support frame.

A freestanding dual-scale lever balance is also supplied to support several of the demonstrations.

This unit has been designed to demonstrate the hydraulic characteristics and settling efficiencies of

a model settling basin. Although scale-up to industrial size sedimentation tanks is difficult, relevant

deductions can be made as to how non-uniform flows occur and how these interact with the settling

characteristics of particular suspensions.

Demonstration Capabilities:

Measuring flow short-circuiting and dead space using a tracer

Comparison of real flow regimes with idealized flow models

Effect of flow rate and baffle position on dispersion

Measuring sediment removal efficiencies and relating these to the hydraulic characteristics
